4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mathieu Malaterre <malat@xxxxxxxxxx>
commit 81bd415c91eb966118d773dddf254aebf3022411 upstream.
The split out of the hard lockup detector exposed two new weak functions,
but no prototypes for them, which triggers the build warning:
kernel/watchdog.c:109:12: warning: no previous prototype for ‘watchdog_nmi_enable’ [-Wmissing-prototypes]
kernel/watchdog.c:115:13: warning: no previous prototype for ‘watchdog_nmi_disable’ [-Wmissing-prototypes]
Add the prototypes.
Fixes: 73ce0511c436 ("kernel/watchdog.c: move hardlockup detector to separate file")
